Selenium ke setsi sa mmele, se bolelang hore 'mele oa hau o hloka chelete e nyane feela. Selenium le liprotheine lia kopana ho etsa li-anti-oxidants tse bitsoang selenoproteins tse thusang ho sireletsa lisele tsa 'meleng oa hao ho tsoa tšenyo e khōlō ea mahala. Selenium e boetse e le ea bohlokoa bakeng sa ts'ebetso ea qoqotho e tloaelehileng, ea ho ikatisa le ea DNA.
Selenium e fumanoa lijong tse ngata tse thehiloeng limela, tse kang lijo tsohle le linate, hammoho le lijo tse ngata tse thehiloeng liphoofolong.
Lijo tsa leoatleng le liphoofolo tsa nama ke mehloli e ruileng ka ho fetisisa, e lateloang ke lijo, lijo-thollo le lebese. Lihe, tlhapi le likhoho, li fana ka lijo tse tloaelehileng haholo.
Likolo tsa National Academy of Sciences, Engineering, le Medicine, Health le Medicine Division li beha Dietary Reference Intakes (DRIs) bakeng sa divithamini le liminerale. Li-DRI tsa selenium li thehiloe ho lilemo, hammoho le basali ba nang le moimana kapa ba anyesang ba hlokang ho hong ho eketsehileng.
Li-DRI tsena li bontša boholo ba selenium bo hlokahalang ke motho ea phelang hantle. Haeba u na le maemo afe kapa afe a bophelo, u ka 'na ua batla ho bua le mofani oa tlhokomelo ea bophelo ka litlhoko tsa hau tsa lijo, ho akarelletsa le selenium.
Dietary Reference Intakes
Lilemo tse 1 ho isa ho tse 3: micrograms tse 20 ka letsatsi
Lilemo tse 4 ho isa ho tse 8: micrograms tse 30 ka letsatsi
Lilemo tse 9 ho isa ho tse 13: micrograms tse 40 ka letsatsi
Lilemo tse 14+: micrograms tse 55 ka letsatsi
Basali ba nang le moimana: micrograms tse 60 ka letsatsi
Basali ba anyesang: li microgram tse 70 ka letsatsi
Ho haella ha Selenium ha hoa tloaeleha linaheng tse tsoetseng pele hobane li fumaneha habonolo lijong. Batho ba tšoeroeng ke lefu la liphio tse hlokang hemodialysis le li-AID li ka 'na tsa e-ba kotsing e kholo ea ho haella.
Melemo le liphello tse mpe tsa ho nka li-Supplemental Selenium
Liphuputso tse ling li bontša hore ho ka 'na ha e-ba le kotsi e tlaase ea mefuta e meng ea kankere le lefu la pelo har'a batho ba jang selenium tse ngata lijong tsa bona.
Empa lipatlisiso tse ling li hlokahalang ho fumana hore na ho noa selenium li-supplement, ka linako tse ling li rekisoa e le li-antioxidants, li molemo. Phuputso e 'ngoe ea lipatlisiso le li-micrograms tse 100 tsa selenium tse bontšitsoeng ho nka li-antioxidant supplements ha li bonahale li fana ka melemo ea bophelo bo botle.
Selenosis (ho na le selenium e ngata haholo 'meleng oa hao) e fella ka matšoao a masapo, ho lahleheloa ke moriri, litlolo tse tšoeu tse tšoeu, konofolo ea monko o khathollang, mokhathala, ho halefa le ho senyeha ha pelo. Setsi sa National Academy of Sciences se behile lijo tse phahameng tse mamellehang bakeng sa selenium ho micrograms tse 400 ka letsatsi bakeng sa batho ba baholo.
Hangata chefo ea selenium e bakoa ke ho sebelisoa ha indasteri ea selenium, eseng ka ho nka li-supplement, empa ho ka khoneha ho noa selenium haholo haeba u lula u nka litekanyetso tse kholo.
Buisana le ngaka ea hau pele u nka tekanyo e kholo ea lijo tse ling tsa lijo, ho akarelletsa le selenium, mme u latele litaelo tse hlahang ho lihlahisoa tsa sehlahisoa.
